To all whom it may concern..-

Be it known that I, J OSEPH A. DIETZ, a citi-, zen of the United States, residing at Kersey, in the county of Elk and State of Pennsylvania, have invented certain new and useful Improvements in Screens for Doors and Windows, of which the following is a specification.

My invention relates to improvements in fly-screens for doors and windows.

Among other objects had in view by my invention it is adapted to provide for the escape of flies or insects from within the house and to effect the entrapping thereof .in their flight and to carry out these ends in a simple, economic, and eflective manner.

Said invention consists of the structural features substantially as hereinafter fully disclosed and particularly pointed out by the claims.

In the accompanying drawings, illustrating the preferred embodiment of my invention, Figure 1 is a front elevation thereof. Fig. 2 is a sectional elevation of the same produced through certain of the fly-exits. Fig. 3 is a transverse section viewing toward the top end of the screen. Fig. 4 is also an elevation viewing toward the interior. Fig. 5 is a detached perspective view of two of the semi tubular formations of the fly exits or passages.

In carrying out my invention I employ duplicate screen-frames 1 2, which are hinged together along longitudinal edges, as at 3, and are normally arranged back to back, one frame having suitably applied or secured thereto wirecloth 3 of the desired mesh or gage for the intended purpose forming the outer surface of the screeen. This frame has an opening 4 through its top bar, and upon the upper surface of the latter is suitably secured or retained around-said opening a preferably wire-cloth open-tube, 5, the exit of which is to be closed in any suitable manner for iniprisoning the entrapped flies.

The opposite frame 2 has secured transversely thereon, about at its mid-length, a cross-bar 6 and at its extreme top end a like cross-bar 7, both of said cross-bars being set into notches or -recesses in the inner longitudinal edges of said frame, thus disposing them flush with the latter.

Sections or pieces of wirecloth 8 9 arealso applied to the frame 2, the same being arranged within the plane thereof and suitably secured to lateral strips or cleats 10, themselves being secured to the inner sides of said frame in inclined positions with their upper ends projecting in under and spaced from the wire-cloth sections 8 are arranged about flush with the outer surface of the cross-bar 6 and the corresponding surface of the bottom crossbar of the frame 2, respectively. Said crossbars 6 7 have produced vertically therein grooves or recesses 11 12, respectively, the wire-cloth sections covering the latter, and arranged at the upper ends of each two of the recesses or grooves in each cross-bar are horizontal semitubular formations 13 14:, respectively, constituting fly or insect exits, as will presently more fully appear, with their open sides presented downward and covered by continuations of the wire cloth sections. Thus by the aforesaid arrangement of parts inward-projecting or right-angled continuations of the passages or outlets produced by the wire-cloth-covered recesses or grooves are formed for the passing of the flies into the chamber produced by the wire-cloth-equipped and hinged-together frames. The semitubular formations 13 14 are made in common from a single strip of metal 15 16, respectively secured upon the upper edges of the crossbars 6 7, respectively.

The thus formed double screen has its hinged-together sections suitably clasped or held together by a clasp or hook 17, pivoted to one screen-section and engaging a staple 18 or the like secured in the other screen-section.

It is apparent from the foregoing that the flies or insects from the room or apartment passing or traveling along the inner surface of the screen and upward through the passages or exits, as above described, will be conducted by the horizontal continuations thereof into the interior of the screen-chamber aforesaid, whence in their attempt to escape therefrom they will naturally fly or pass upward and along the under side of the frame top bars and finally enter through the opening in one of the latter the cage thereabove, with which said opening communicates, and be imprisoned therein for suitable disposition.

I claim 1. A window or door screen, comprising wire cloth covered connected together frames conjointly forming a chamber having fly or insect ingress-openings and an insect or fly exit opening, said ingress-openings consisting of vertical grooves formed in cross-bars of one screen-frame and of angular tubular continuatlons oi said grooves extending into said chamber.

2. A door or WindoW- screen, comprising Wire cloth covered connected together frames forming a chamber, one of Which has its screen-forming sections secured at their upper ends to cross-bars provided With vertical grooves and with semitubular formations
